[PATCH] doc: Don't echo sed command for manpage-base-url.xsl

[Tim Schumacher <timschumi@gmx.de>]

Previously, the sed command for generating manpage-base-url.xsl
was printed to the console when being run.

For the purpose of silencing it, define a $(QUIET) variable which
contains an '@' if verbose mode isn't enabled and which is empty
otherwise. This just silences the command invocation without doing
anything else.
